It’s about 5-10 mins. And it’s pretty loud. I only have 1026 miles on it.

Take it to the dealer

So we have a Monday , December 21 engine build after Angelo's Monday November 15th in the next post. IE 5 weeks apart we go from -AA TO REVISION -AB . What's the difference?

They are different part #s that's why we wanted to see

Yeah I seen that mine is 121 and his is 161 wonder what’s different

look at 21319 in the middle of your smaller print. vs 21356 in the other one from Iceage (GG) these are Nov 15th yours and Dec 21st GG's for when the engines were built in the Lima Engine Plant.

What we don't know and why we are interested is the the suffix has changed ( last 2 characters -AA on yours and _AB on GG's . What changed to have the configuration part number revision update? Some of us that have not yet had our Bronco's built are hoping that the -AB is a meaningful valve change.

We don't know! And the suffix ( last 2 characters -AA on yours and _AB on GG's is our question? What changed to have the configuration part number revision update?

His is a 22 a d mine is a 21 wonder if that has something to do with it too the mystery continues lol

I thought some one said the a and ab were the lines the engine was built on maybe not sure

Yours is MB3E-6007-AA, @Ice Age has MB3E-6007-AB. we are exploring the idea that -AB is a supersession. Don't read too much into it, because supersessions happen alot...for lots of dumb reasons. Now...I know it was covered somewhere else, but do we have some replacement part #s? Yes I know the basic changes to 6006...not worried about that. Wanna know the suffix

it was my question and I was not sure but believe it may be more than that?
